Alpins method
The Alpins Method, developed by Australian ophthalmologist Noel Alpins, is a system to plan and analyze the results of refractive surgical procedures, such as laser in-situ keratomileus (LASIK).[1][2][3] The Alpins Method is also used to plan cataract/toric intraocular lens (IOL) surgical procedures.[4]
Introduced in 1993, it has been used in some research studies of LASIK.[1][2][3][5] In 2006 the American National Standards Institute (ANSI) published guidelines based on the Alpins Method, designed to help manufacturers demonstrate the efficacy of refractive surgical lasers.[3][6][7]
The Alpins Method uses vector mathematics to determine a goal for astigmatism correction and analyze factors involved if treatment fails to reach that goal. The method can also be used to refine surgical techniques or correct laser settings in future procedures.[8] The Alpins Method is one of the “more sophisticated” approaches in analyzing surgical results.[1]
